## Implementation

### File Structure
```
resources/views/auth/
├── login.blade.php              # Main login page (updated)
└── developer-login.blade.php     # Developer login page (new)
```

### Route Configuration
```php
// Developer Login Route
Route::get('/developer/login', function () {
    return view('auth.developer-login');
})->name('developer.login');
```

### Middleware Integration
The DeveloperMiddleware has been updated to redirect unauthorized users to the developer login page:

```php
// Before: redirect()->route('login')
// After: redirect()->route('developer.login')
```

## Access Flow

### User Journey
1. **Access Developer Login:** User visits `/developer/login`
2. **Enter Credentials:** User enters email and password
3. **Form Submission:** Form submitted with CSRF token
4. **Authentication:** Laravel authenticates user credentials
5. **Role Check:** DeveloperMiddleware checks user role and permissions
6. **Redirect:** User redirected based on authorization status

### Redirect Logic
```php
if (!Auth::check()) {
    return redirect()->route('developer.login')->with('error', 'You must be logged in to access the developer dashboard.');
}

if (!Auth::user()->hasRole('developer')) {
    if (Auth::user()->hasRole('admin')) {
        return redirect()->route('admin.dashboard')->with('error', 'Access denied. This area is restricted to developers only.');
    }
    return redirect()->route('developer.login')->with('error', 'Access denied. You do not have permission to access the developer dashboard.');
}

if (!Auth::user()->can('developer.dashboard.view')) {
    return redirect()->route('developer.login')->with('error', 'Access denied. You do not have the required permissions to access the developer dashboard.');
}
```

- **Solution:** Clear view cache: `php artisan view:clear`

### Debug Mode
Enable debug mode for detailed error messages:
```php
// .env
APP_DEBUG=true
```

### Log Files
Check Laravel logs for authentication issues:
```bash
# Check Laravel logs
tail -f storage/logs/laravel.log

# Check developer-specific logs
grep "developer" storage/logs/laravel.log
```
